Compactor using compaction value targets

Abstract

A compaction monitoring system for a compactor has one or more sensors, a positioning system and a controller. The sensors are configured to transmit signals representative of one or more characteristics of a material related to a compaction value of the material. The positioning system may be configured to transmit a location signal representative of a position of the compactor. The controller may be configured to receive the signals from the one or more sensors, determine compaction values of the material based on the signals from the one or more sensors using a proof-rolling method, and determine the position of the compactor based on the location signal transmitted by the positioning system. The controller may also be configured to generate a compaction value profile based on compaction values of the material and the position of the compactor, compare the compaction value profile to stored compaction value target information, determine a difference between the compaction value profile and the compaction value target information, and output information based on the difference between the compaction value profile and the compaction value target information.

Description

TECHNICAL FIELD [0001] The present disclosure is directed to a compactor, and more particularly, to a compactor using compaction value targets. BACKGROUND [0002] Preparation of roadways, building sites, embankments and other surfaces often requires compaction to produce desired material properties. To facilitate material compaction, compactors are often employed to compact soil, gravel, asphalt, and other materials. Such compactors may include, for example, rotating drum compactors in which one or more rotatable drum assemblies roll over the material to be compacted. The drum assembly, or roller, may include a static roller system in which the weight of the compactor and drum produces the compaction. Alternatively, compactors may include a vibratory mechanism having weights arranged within an interior cavity of the drum for inducing vibrations to enhance the compaction process. The vibratory mechanism may include a range of frequency and / or amplitude settings selected based on the c...

AI Technical Summary

Benefits of technology

The present patent is about a system and method for monitoring a compaction process. The system includes sensors that collect data on the material being compacted, a positioning system that tracks the location of the compactor, and a controller that analyzes the sensor data and determines the compaction value of the material based on a proof-rolling method. The controller also generates a profile of the compaction values and compares it to pre-defined target information. The system can output information based on the difference between the two. The technical effect of this patent is to provide a more accurate and efficient way to monitor compaction processes.

Problems solved by technology

However, these methods may only evaluate limited portions of a compacted material.

Further, these methods may be time consuming as they are usually conducted separate from the compaction process.

Further, materials exhibiting dynamic vibrational responses may not correlate with the ability of the material to statically and rigidly support loads.
